EDWARD E. LORENZ BYWA/M CARBURETOR IDLE LIMITER TOOL BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a carburetor idle limiter tool and more particularly to a carburetor idle limiter tool for installing and removing a carburetor idle limiter in situ.

According to the invention, a carburetor idle limiter tool is provided in which an elongated generally S- shaped rod has an insertion fitting contiguous with one end thereof and a withdrawal fitting rotatably carried by another end thereof, Because of the crowded condition under the hood of a modern vehicle and, particularly, in proximity to the carburetor, it has been found that the use of this tool results in a heavy savings of both insertion and removal time of the carburetor idle limiter. The elongated rod provided has two hammer stops attached between its ends and a hammer slidably carried by the rod. The hammer stop is utilized in conjunction with the end furthest removed therefrom so that the part may be hammered in and out in an area removed from the carburetor and other equipment mounted in proximity to the carburetor. Hence, the sliding hammer has a key slot which accommodates one of the hammer stops and enables the hammer stop to be moved on either side of it for access to the other hammer stop.

An object of the present invention is the provision of an improved carburetor idle limiter tool.

Another object of the invention is the provision of an improved carburetor idle limiter tool for the insertion and removal of carburetor idle limiters.

Yet another object of the invention is the provision of an improved carburetor idle limiter tool providing hammering surfaces in the insertion and withdrawal of the carburetor idle limiter remotely located to equipment mounted in proximity to the carburetor.

A still further object of the invention is the provision of an improved carburetor idle limiter tool which is inexpensive to manufacture and extremely convenient in use.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which like reference numerals designate like parts throughout the FIGS thereof and wherein:

FIG. 1 is a perspective view of the preferred embodiment of the present invention;

FIG. 2 is a perspective view of the embodiment of FIG. 1 rotated 90;

FIG. 3 is a perspective view of the insertion fitting in alignment with a carburetor idle limiter;

FIG. 4 is an end view of a typical carburetor idle limiter engaged with the insertion fitting of FIG. 3; and

FIG. 5 is a perspective view of the withdrawal fitting in alignment with a typical carburetor idle limiter.

DETAILED DESCRIPTIONOF THE DRAWINGS Referring to FIG. 1. the carburetor idle limiter tool is shown generally at ll having'an elongated rod 12 with insertion fitting l3 fixedly attached as by brazing at one end thereof, and withdrawal fitting 16 which is rotatably attached (not shown) to rod 12. Withdrawal hammer stop 17 is fixedly attached and carried by rod 12 as is insertion hammer stop 19, having a hammer surface 14. Hammer 18 is slidably carried by rod 12.

Referring to FIG. 2, the general S-curved shape of rod 12 is more clearly illustrated as is key channel 21 in hammer 18 dimensioned for sliding over hammer stop 19. Withdrawal fitting 16 is illustrated in more detail having an annular retaining groove 22 in rod 11 accommodating retaining pin 23 which is carried by insertion fitting 16. Insertion fitting I6 terminates in a withdrawal cup 24 with a withdrawal lip 26.

Referring to FIG. 3, insertion fitting 13 is shown with a spatially disposed carburetor idle limiter comprising a thimble-like body 27 with an outer end 28 and an inner end surface 29. Inner end surface 29 surrounds an in terior cavity 31 and body 27 carries a tab 32.

Referring to FIG. 4, an end view of idle limiter 27 is shown engaged with insertion fitting 13. Tab 32 is received by tab clearance slot 34 with the driving end 36 of rod 12 viewed through a cruciform opening 33 in the outer end of carburetor idle limiter 27.

Referring to FIG. 5, withdrawal fitting 16 is shown in spatial relationship with carburetor idle limiter 27. Withdrawal cup 24 is dimensioned for receiving limiter 27. Lip 26 engages outer surface 29 oflimiter 27.

OPERATION For inserting carburetor limiter 27 into a carburetor, carburetor limiter 27 is engaged with insertion fitting 13 as shown in FIG. 4. Limiter 27 is then placed in proximity with the mating carburetor aperture and hammer 18 is positioned for contact with hammer surface 14 of hammer stop 19, i.e., key channel 21 is not aligned with hammer stop 19. Hammer 18 can then be hammered against surface 14 forcing limiter 27 into the carburetor.

When it is desired to remove limiter 27, the tool is reversed and withdrawal fitting 16 is rotated into position over limiter 27. When lip 26 is in contact with inner end surface 29 of limiter 27, hammer I8 is then rotated for passage of channel 21 over hammer stop 19 and hammer 18 is moved along rod 12 until it is in contact with withdrawal hammer stop 17. At this time, the same end surface of hammer 18 can be hammered withdrawing carburetor idle limiter 27.

The general S-shape of rod 11 has been found empirically to afford the most utility in the various models of modern automobiles with their variously crowded underhood conditions.

It should be understood of course that the foregoing disclosure relates to only a preferred embodiment of the invention and that it is intended to cover all changes and modifications of the example of the invention herein chosen for the purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.

The invention claimed is:

l. A carburetor idle limiter tool comprising:

an elongated S-shaped rod; and

a withdrawal fitting rotatably attached to one end of said rod, said withdrawal fitting having a lip dimensioned for cooperation with an inside surface of a carburetor idle limiter;

hammering means carried by said rod for hammering said withdrawal fitting away from said one end; and

an insertion fitting contiguous with another one end of said rod, said insertion fitting having a cylindrical body with a slot therein for receiving a carburetor idle limiter. 

1. A carburetor idle limiter tool comprising: an elongated S-shaped rod; and a withdrawal fitting rotatably attached to one end of said rod, said withdrawal fitting having a lip dimensioned for cooperation with an inside surface of a carburetor idle limiter; hammering means carried by said rod for hammering said withdrawal fitting away from said one end; and an insertion fitting contiguous with another one end of said rod, said insertion fitting having a cylindrical body with a slot therein for receiving a carburetor idle limiter.
